Abstract
A method and apparatus for smoothing raw oscillometric table data in the region around systolic blood pressure to reduce respiration interference is disclosed. Systolic blood pressure is determined by averaging intermediate systolic pressures calculated in association with dual thresholds instead of a single threshold. Interpolation is used between adjacent applied cuff pressure values having table entries located on either side of each of the upper and lower threshold values. Normalization of the table is employed to improve interpolation resolution.
